I wasn't clear on how was using "better". Your example is better in that it fulfills the requirement, but I don't think it's as impressive as ChatGPT's answer. How long would it take to make a sentence that is at least 7 words (and also making sense, and ideally sounding good)?

In 5-10 minutes I came up with "Alarm! Naked actor moons queen below (under?) fruit trees, later hides under cheap hotel floor".

Note that I used one of those minutes to get a list of all 4 and 5 letter words, which I'm not sure whether the rules allow or not.

It would take me longer to write an interesting, longer sentence that complied with the rules. But I'd remind you that GPT failed.

"That's" is not one word.

This isn't something that can be usefully discussed. "Word" has a vague enough definition that a contraction can validly be considered one or two words. If you try and look to linguistics you'll just see they use specialized words with stricter definitions.

Regardless it's more reasonable for me to say "that's" is a five letter word than it is for the AI to say "spells" is a five letter word.
